@b23vnodev, the 4 hours is for development only. You can design and analyse anyway you want in this 1 week period.
@Jay, you have an extra hour to get the executable ready for each one of your submissions. If this is not enough, we can change this rule for future jams.
@adrianm, I don’t want to lead anyone so if you don’t want, please stop reading.
[spoiler]Actually, the idea came from an early PC classic, Ultima series. As Ultima Online from the series is my reason to start game programming, I figured it would be a good point to start. If you get stuck, you can always take a look at the series for inspiration.[/spoiler]
